The objective of the present invention is to provide a lifting/lowering device for a load, the device being capable of stably lifting/lowering a load by using one lifting/lowering driving means. In order to implement same, the lifting/lowering device for a load, of the present invention, has a lifting/lowering driving part for vertically lifting/lowering a load, wherein the lifting/lowering driving part comprises: the lifting/lowering driving means for generating driving force for vertically lifting/lowering the load; a first power transmission part including a first power transmission member of which the vertical position is changed so that vertical lifting/lowering force is applied to one side of the lower portion of the load, when a first rotary shaft rotating by means of the driving force of the lifting/lowering driving means rotates; and a second power transmission part including a second power transmission member of which the vertical position is changed so that vertical lifting/lowering force is applied to the other side of the lower portion of the load, when a second rotary shaft rotating by means of the driving force of the lifting/lowering driving means rotates.

    L'objectif de la présente invention est de fournir un dispositif de levage/abaissement pour une charge, le dispositif pouvant soulever/abaisser de manière stable une charge à l'aide d'un moyen d'entraînement de levage/abaissement. À cet effet, le dispositif de levage/abaissement pour une charge, selon la présente invention, comporte une partie d'entraînement de levage/abaissement pour soulever/abaisser verticalement une charge, la partie d'entraînement de levage/abaissement comprenant : le moyen d'entraînement de levage/abaissement pour générer une force d'entraînement pour soulever/abaisser verticalement la charge ; une première partie de transmission de puissance comprenant un premier élément de transmission de puissance dont la position verticale est modifiée de telle sorte qu'une force de levage/abaissement verticale est appliquée à un côté de la partie inférieure de la charge, lors de la rotation d'un premier arbre rotatif tournant sous l'effet de la force d'entraînement du moyen d'entraînement de levage/abaissement ; et une seconde partie de transmission de puissance comprenant un second élément de transmission de puissance dont la position verticale est modifiée de telle sorte qu'une force de levage/abaissement verticale est appliquée à l'autre côté de la partie inférieure de la charge, lors de la rotation d'un second arbre rotatif tournant sous l'effet de la force d'entraînement du moyen d'entraînement de levage/abaissement.

    본 발명은 하나의 승강구동수단을 이용하여 적재물을 안정적으로 승강시킬 수 있는 적재물 승강장치를 제공함에 그 목적이 있다. 이를 구현하기 위한 본 발명의 적재물 승강장치는, 적재물을 상하로 승강시키는 승강구동부가 구비된 적재물 승강장치에 있어서, 상기 승강구동부는, 상기 적재물을 상하로 승강시키기 위한 구동력을 발생시키는 승강구동수단; 상기 승강구동수단의 구동력에 의해 회전하는 제1회전축의 회전시 상하 위치가 가변되어 상기 적재물의 하부 일측에 상하 방향으로 승강시키는 힘을 작용시키는 제1동력전달부재를 포함하는 제1동력전달부; 상기 승강구동수단의 구동력에 의해 회전하는 제2회전축의 회전시 상하 위치가 가변되어 상기 적재물의 하부 타측에 상하 방향으로 승강시키는 힘을 작용시키는 제2동력전달부재를 포함하는 제2동력전달부를 포함한다.
